discov_num notes refcode
GNS 3 Ginski et al. (2012) conclude the companion is physical, and estimate
the mass at 0.239 +/- 0.022 Msun. Gns2012
Ginski et al. (2016) resolved the B component into a ~100 mas pair of
similar magnitude. Masses of Ba and Bb are estimated at 0.165 +/-
0.008 and 0.154 +0.009/-0.008 Msun. Gns2016
CHARA Array Limb-darkened diameter 0.480 +/- 0.033 mas. CIA2009a
R = 2.59 +/- 0.19 \rsun, L = 4.7 +/- 0.1 \lsun,
Teff = 5283 +/- 186 K.
